The “free lunch” in the saying refers to the formerly common practice in American bars of offering a ‘free lunch’ to entice drinking customers.

Definition. The NFLT was proposed back in 1997 by Wolpert and Macready. It states that no universally better algorithm can solve all types of optimization problems. We should keep in mind that whenever we talk about optimization, we’re including but not limiting the usability of this theorem to machine learning. WebApr 1, 1997 · A number of “no free lunch” (NFL) theorems are presented which establish that for any algorithm, any elevated performance over one class of problems is offset by performance over another class. These theorems result in a geometric interpretation of what it means for an algorithm to be well suited to an optimization problem. gsps for sale north carolina

The No Free Lunch theorem (NFL) was established to debunk claims of the form: My optimisation strategy X is always best. In particular, such claims arose in the area of genetic/evolutionary algorithms. The statement is, roughly: every optimisation strategy performs badly on many problems. Therefore, there can be no always-best strategy and ...
